    Hfss bug?Different angle, different result.

    I have used the coax instead of the port in this model，but result is the same. I really can't understand it. If it is a bug, is anybody can give me a hand?

    Hfss bug?Different angle, different result.

    Hi, maybe I find a bug in Hfss. A patch on the outside surface of a cylinder, at first, the resonance frequency is 2.45G, then rotate the patch about the z-axis 12 degree, and get a different resonance frequency :2.20G. And I find when the angle is 45,90, 135 and so on, the resonance frequency...

    Hfss error:the lumped port can not touch the ground,help needed!

    the lumped port can't touch the ground in my model,I have trid to expand the port, but it still get the error: "Fast sweep setup, process hf3d: '1' conductors touch lumped port '1', typically a lumped port contains 2 conductors. Please verify conducting boundaries and objects are correctly...

    Help! hfss err: Typically a lumped port contains 2 conductors ...

    Thanks! I understand it: the inside and out side of the surface should be circular, but it is represented by polygons, so the radius of the inside surface is not 77mm which it should be, so the port does not touch the ground. Now I don't konw how to let the port touch the ground, I try to draw...

    Help! hfss err: Typically a lumped port contains 2 conductors ...

    Hi, I want to design a patch on the outside surface of a cylinder(Please check the attached file), it includes only one port, which connects the inside and outside surface. Then I get an err:"Fast sweep setup, process hf3d: '1' conductors touch lumped port '1', typically a lumped port contains...
